10) 25 : 24

11) 24 : 5

12) 36 : 5

13) 7 : 3

14) 15 : 1

<u>Ratio = Number of event 1 : Number of event 2</u> (in same unit, if necessary)

<u>10</u>

Girls preferring orange juice : Boys preferring orange juice

50 : 48 (Divide by 2 on both sides)

25 : 24

<u>11</u>

Boys preferring orange juice : Boys preferring grapefruit juice

48 : 10 (Divide by 2 on both sides)

24 : 5

Remember :

  • <u>1 minute = 60 seconds</u>
  • <u>1 week = 7 days</u>
  • <u>1 hour = 60 minutes</u>

<u />

<u>12</u>

3 minutes : 25 seconds

3 × 60 : 25 (Divide by 5 on both sides)

3 × 12 : 5

36 : 5

<u>13</u>

2 weeks : 6 days

2 × 7 : 6 (Divide by 2 on both sides)

7 : 3

<u>14</u>

5 hours : 20 minutes

5 × 60 : 20 (Divide by 20 on both sides)

5 × 3 : 1

15 : 1

Using these complex zeros (1,1,-1/2,2+i,2-i) factor f(x)=-2x^5 +11x^4 -22x^3 +14x^2 +4x -5
Marianna [84]
\bf \begin{cases}&#10;x=1\implies &x-1=0\\&#10;x=1\implies &x-1=0\\&#10;x=-\frac{1}{2}\implies 2x=-1\implies &2x+1=0\\&#10;x=2+i\implies &x-2-i=0\\&#10;x=2-i\implies &x-2+i=0&#10;\end{cases}&#10;\\\\\\&#10;(x-1)(x-1)(2x+1)(x-2-i)(x-2+i)=\stackrel{original~polynomial}{0}&#10;\\\\\\&#10;(x-1)^2(2x+1)~\stackrel{\textit{difference of squares}}{[(x-2)-(i)][(x-2)+(i)]}

\bf (x^2-2x+1)(2x+1)~[(x-2)^2-(i)^2]&#10;\\\\\\&#10;(x^2-2x+1)(2x+1)~[(x^2-4x+4)-(-1)]&#10;\\\\\\&#10;(x^2-2x+1)(2x+1)~[(x^2-4x+4)+1]&#10;\\\\\\&#10;(x^2-2x+1)(2x+1)~[x^2-4x+5]&#10;\\\\\\&#10;(x^2-2x+1)(2x+1)(x^2-4x+5)

of course, you can always use  (x-1)(x-1)(2x+1)(x²-4x+5)  as well.
